The Carl Zeiss Tele-Tessar 500mm f8 is a telephoto lens for Hasselblad V-series cameras. In excellent condition, with only minor cosmetic wear. Shutter speeds are good, glass has minor dust. Not something you want to carry around with you every day- it weighs a couple of kilos and it's almost 40cm long- but if you've gotta get your Rear WIndow on an all you have is a Hasselblad, this is the lens you want.
